For my environment (TSM 6.2.3 on Aix 7.1 TL1 SP3) this fix is to disable the lo_perf network option and reboot.
no -p -o lo_perf and a reboot later I was back to speedy DB backups. Just did this last Friday... The tech I talked to said this problem affects Aix 6.1 TL7 and Aix 7.1 TL1. I did not have a problem when I was at Aix 7.1 TL0 SP4.
